CARBURETED-AIR MACHINE.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed December 3, 1904:. Sen'al No. 235,327-

To all whom, it may concern:

Be it known that I, FIRMIN PIOARD, a subject of the King of Great Britain, and a resident of Montreal, in the Province of Quebec and Dominion of Canada, have invented new and useful Improvements in Carbm-eted-Air Machines, of which the following'is a full, clear, and exact description.

My invention relates to carbureted-air machines; and it consists in the various features and combinations hereinafter described and more particularly claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 shows a vertical longitudinal section of an apparatus constructed in accordance with my invention, it being taken on the line 1 1 of Fig. 2. Fig. 2 is a transverse vertical section on the line 2 2 of Fig. 1, and Fig. 3 is a longitudinal section on the line 3 3 of Fig. 2 and including a receiving-tank.

1O designates a fluid-tight tank or casing which is divided by a longitudinal partition 11 into a liquid or vaporizing chamber 12 and a motor-chamber 12. In the upper portion of the vaporizing-chamber is formed a fanchamber 13 by means of walls 14C. The opposite sides of the vaporizing-chamber carry alined bearings 15, in which is journaled a shaft 16. This shaft has fast upon it vaporizing members, here shown as two in number and furnished by spiders 17, carrying absorbent material, which may consist of sheets 18 of some such fabric as canvas, this being attached to each spider at both its inner and outer face. From the peripheries of the spi ders pins or projections 19 extend toward the companion spider, furnishing supports for strips 20 of the fabric.

Leading from the fan-chamber into the vaporizing-chamber is a conduit 21, having divided ends 22, which lie within the projections 19 of the covering of the vaporizing members and open, by means of enlarged or bell-shaped nozzles 23, toward the sheets 18. Connected with the conduit is a blast apparatus or fan 24, having its shaft extending through the partition 11 into the motor-chamber, while from its side an inlet-pipe 26 leads through the casing to the atmosphere.

\Yithin the chamber 12 is situated a motor 27, which, as illustrated, is of the hydraulic type and has a power-shaft 28 journaled in bearings in the partition 11 and in the outer wall of the casing. Upon this power-shaft is tixed a gear 29, meshing with a pinion 30 upon a shaft 31, carried by a bearing mounted upon the partition 11 and passing through it into the vaporizirig-chamber. At its inner extremity this shaft has secured to it a pinion 32, which coacts with a gear 33, carried by the adjacent vaporizing member. It also has rotating with it within the chamber 12 a gear 3& meshing with a pinion upon the fan-shaft. The ratio of this gearing is such that while the vaporizing member is turned at a comparatively slow speed the fan is rotated rapidly to produce a blast. Extending through the casing and delivering to the motor is shown a feed-pipe 36, passing through a valve-casing 37, which may be mounted upon the top of the main casing. From the motor and through the casing 10 opens a discharge-pipe 37. From the valve-casing to the discharge-pipe leads a waste-pipe 38. In this particular embodiment of my invention the rotation of the motor is governed by means of a valve 39, operating within the easing 37 and movable to close either the feedpipe or the waste-pipe. It is provided with a stem 40, extending through a stufling-box a1, and is operated as will be hereinafter described. Through the top of the casing 10 is a supply-opening, in which may be inserted a short section of pipe 12, the upper end of which may be closed by a plug 43, while with the lower end coacts a valve 1%, which may be hinged at one side and be held normally closed by a spring 45. From the bottom of the vaporizing-chamber may lead a draw-ofi' pipe 16, containing a cock 17. A gage-glass 48 is preferably provided to show the height of the contained liquid. Connected with the top of the vaporizing-chamber is a carburetedair outlet pipe 49, which extends downwardly and enters the lower portion of a receiving-tank 50, through which it rises, and is provided with an upper bent end 51. A carbureted-air-supply pipe 52 extends from within the receiving-tank at a point above the outlet of the pipe t9 through the bottom of the receiving-tank and serves to deliver the contained carbureted air to the place at which it is to be used, it preferably including a valve 53 for shutting off the supply.

The receiving-tank, as shown, has moving within it the usual bell 54, which is provided at one side with lower and upper projections 55 and 56, respectively, which have adjacent squared faces 56. Movable in guides 57,

conveniently secured to the receiving-tank, is a controlling member or rod 58, having an angular end portion 59 pivoted upon it and held normally inward into coaction wit-h the bell by a spring 60. This angular portion upon its side toward the projection has a somewhat-inclined face 61. Projecting from the controlling-rod is a pin 62, extending into a slot in one extremity of an angle-lever 63, fulcrumed upon a bracket 64, which may be carried by the valve-casing, and having its opposite end attached to the valve-rod.

The vaporizing-chamber is supplied through its feed-opening with the liquid from which the carbureted air is to be generated, this preferably consisting of a mixture of ninety-three per cent. of some such volatile hydrocarbon as gasolene and seven per cent. of methyl alcohol, this being inexplosive and in no way dangerous and which forms a gas the lighting and heating powers of which are greatly superior to gasolene alone. Moreover, the flame of the burning carbureted air offers a better resistance to currents of air. The quantity as shown by the gage should be suflicient to bring the level somewhat above the shaft of the vaporizing member. The receiving-tank is supplied with water preferably containing at least three per cent. of glycerin to serve as a deodorant. The level of this liquid body within the receiving-tank must be above the depending end of the outlet-pipe 4:9. The bell being in its lowest position and the valve 39 in the position illustrated in Fig. 3 of the drawings, the motive fluid will be delivered to the motor, rotating it and causing the fabric carried by the spiders to pass through the contents of the vaporizing-tank, agitating it and at the same time exposing a thin film ofthe mixture to the blast of air which is delivered through the conduit 21 from the fan. It should be noted that the air-current acts both directly against the covering of the spiders and also, as it is deflected laterally therefrom, against the strip of fabric carried by the projections. The air impregnated with the inflammable vapor flows through the pipe 49 into the receiving-tank and exerting its pressure upon the bell raises it. This continues until the projection 55 contacts with the end of the controlling-rod, which is gradually raised, moving the valve 39 to close the pipe 36 and open the waste-pipe 38. The motive fluid now passes through the apparatus without rotating the motor, and both the movement of the vaporizing member and the rotation of the fan are stopped, checking the generation of gas, which may be prevented from escaping through the fan-conduit by means of a check-valve 65, located therein. After the active production of carbureted air has stopped there might still be some generation from the surface of the hydrocarbon and from the moistened vaporizing members. To prevent this from putting undue strain upon the controlling-rod, the inclined face at 61 may be pressed outwardly by the projection 55, enabling the latter to move by it to a certain extent. As the carbureted air is used the bell falls until the projection 56 strikes the end of the controlling-rod, which is moved downwardly, thereby shifting the valve in the opposite direction, thus closing the waste-pipe and opening the pipe 36. The rotation of the vaporizing members and fan again begins, and the receiving-tank is raised as before.

Although a hydraulic motor has been illustrated and described in connection with my improved apparatus, it will be obvious that any other motive force may be used and its governing device similarly controlled by the movement of the bell.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A carbureted-air machine comprising a casing, separated rotatable supports mounted within the casing and each having projections extending toward the companion support, a strip of fabric mounted upon each of the sets of projections, and a blast'conduit situated between the supports and opening within both of the strips.

2. A carbureted-air machine comprising a casing, a shaft extending through the casing, a support fixed to the shaft and having projections, fabric secured to the face of the support and extending about the projections, and a blast-conduit opening toward the face of the support and within the projections.

3. A carbureted-air machine comprising a casing, a shaft rotatable therein, oppositelysituated absorbent members carried by the shaft, a conduit entering the casing and extending toward both absorbent members, and a blast-fan delivering to the conduit.

4. A carbureted-air machine comprising a casing, a shaft rotatable therein, oppositelysituated spiders fixed to the shaft and each having projections extending toward its companion, absorbent material carried by the spiders and extending about the projections, a conduit entering the casing and opening toward both spiders, and ablast-fan delivering to the conduit.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
